Being number one is a very different challenge to being an assistant or simply being a part of the coaching setup, and many of the names on this list found it hard when they stepped into the hot seat.
Some lasted longer than others in the job, but, at the end of the day, none were cut out to be managing clubs at the highest level.
Press the next page as we, once again, look at some of the worst-performing managers over the past thirty years.
The lowest managerial win percentages for the 49 clubs that have featured in the Premier League at some point in history
George Graham is a pretty remarkable name to find at the top of the list having spent 15 years at Arsenal during two successful spells as a player and manager.
Along the way, Graham managed to pick up two League Cups, an FA Cup and a European Cup Winners’ Cup and was the man who forged their legendary stingy defence which featured the likes of Tony Adams, Steve Bould, Lee Dixon and Nigel Winterburn – but that didn’t stop him from getting the sack.
Admittedly, he was shown the door after being found guilty of receiving money as part of an illegal transfer deal in 1995.
Graham had taken over £400,000 in illegal payments from Norwegian agent Rune Hauge in exchange for signing Pal Lydersen and John Jensen.
Not only had Graham broken the rules during his tenure, but he also struggled to maintain consistency, totalling a 36.61 win percentage.
That being said, Graham may be the anomaly that shows a manager is not always judged solely on his statistics as many still regard him as one of Arsenal’s most successful managers.
Most fans would probably point to Bruce Rioch if asked who is their worst manager in the Premier League era.
